SurplusComputers.com is offering the 3 month Xbox Live kit for $15.99, down from the previous $39.99 price. The reason for the difference is that it is a product from the original Xbox. However, the codes do work on Xbox and Xbox 360 systems and also includes the headset for use of the Xbox Live chat system.

For those unfamiliar with SurplusComputers.com, they are legitimate and have a very good reseller rating.
